Seniors living in their own homes are often deficient in vitamin D, vitamin A, vitamin E, calcium and zinc and occasionally vitamin B1 and vitamin B2. Older adults need more calcium and vitamin D to help maintain bone health. Try three daily servings of vitamin D-fortified low-fat or fat-free milk or yogurt. Other calcium-rich foods include fortified cereals and fruit juices, dark green leafy vegetables and canned fish. These are all great additions to your daily meals, but be sure to take a multivitamin with age-adjusted doses of nutrients for people aged 50 years and older.
